[patch 086/119] hugetlb: expose hugetlbfs_inode_info in header

[akpm@linux-foundation.org]

From: Marc-André Lureau <marcandre.lureau@redhat.com>
Subject: hugetlb: expose hugetlbfs_inode_info in header

hugetlbfs inode information will need to be accessed by code in mm/shmem.c
for file sealing operations.  Move inode information definition from .c
file to header for needed access.
